BIRD-CAGE.

SPECIFICATION forming part of Letters Patent No. 227,195, dated May 4,1880.

Application filed February 25, 1878.

To all whom it may concern:

Be it known that I, ANDREW H. ALvERsoN, of New Haven, in the county ofNew Haven and State of Connecticut, have invented a new lmprovement inBird-Cages; andI do hereby declare the following, when taken inconnection with the accompanying drawings and the letters of referencemarked thereon, to be a full, clear, and exact description of the same,and which said drawings constitute part of this specification, andrepresent, in-

Figure 1, a sectional side view; Fig. 2, a section of the tip.

This invention relates to an improvement in the construction of birdcages such as are made from metal and it consists in the construction,as hereinafter described, and more particularly recited in the claim.

A is the sub-base, formed from sheet metal, and with a vertical flange,at, around its edge. This part forms the pan or bottom of the cage. Overthis a superbase, B, is set, with a vertical flange, C, to set down overthe vertical flange, a, as indicated in solid black, Fig. 1.

The top or upper portion of the superbase extends inward, and to itsinner edge the ver- 4 This construction leaves a close base or pan atthe bottom of the cage and covered outside the vertical wires. Throughthe top of the superbase apertures are made at proper places to receivethe feedcup.

D represents the cup as set into the aperture through the sub-base andresting thereon, and so as to bring the aperture of the cup within thesubbase. Thus the feed is entirely within the sub-base, and the baseserves as a guard to prevent the bird from throwing the shucks out ofthe cage.

Several clasps, e, hinged or attached to the cage, drop down over andengage a projecting portion of the sub-base, as shown, so that-the bodyof the cage is removably secured to the base. A similar clasp, f, hingedto the superbase, passes over the feed-cup, and not only secures the cupin place, but serves to close perforations, and then the inner anglefilled with solder around the ends of the wires, as shown in solidblack, Fig. 2. p

The clasp for the door consists of a single piece of wire doubled intoloop form, secured by the looped end to one of the vertical wires, andthe two ends extending outward and beyond the edge of the door areelastic, and serve as springs to enter between and engage hookedprojections 11, on one of the stationary wires, and so that the door maybe disengaged by pressing the two ends together, as indicated in brokenlines.

I am aware that it is not new to construct a bird-cage with a doublebase, as seen in Patent No. 166,595, or with a close base, as seen inPatent No. 153,111.

I claim- In a metal bird-cage, the sub-base A, having a vertical flange,a, around its edge, the superbase B, having a corresponding verticalflange, C, to overlap the said flange a on the sub-base, and claspingdevices to secure the parts, together with feed-cups D, through andwithin said sub-base, and substantially as described.
